The problem seems to be that the back-end (i.e., the internal mail server) is more strict, i.e., it follows the standards more closely, than postfix and therefore refuses the message. There are lots of reasons why it's best to not accept invalid email. That said, the "easiest" fix is to configure postfix to rewrite the invalid sender address into a valid sender address. For example, an email address cannot end with a . (dot). So the following sender address is invalid [email protected] <-- not valid But if you double quote the local part, the email address is valid "end-with-dot."@example.com <-- valid You might be able to use postfix sender_canonical_maps to rewrite an invalid sender to some other (valid) form. > I'm clueless about postfix, is it the same thing as "James"? Postfix is the Mail Transfer Agent (MTA) used by CipherMail. The MTA is responsible for sending and receiving email. James is a mail server which is internally used (the back-end) to encrypt/decrypt etc. received email (Internet -> Postfix -> internal MTA -> Postfix -> Internet) Kind regards, Martijn Brinkers -- CipherMail email encryption Email encryption with support for S/MIME, OpenPGP, PDF encryption and secure webmail pull. https://www.ciphermail.com Twitter: http://twitter.com/CipherMail _______________________________________________ Users mailing list [email protected] https://lists.ciphermail.com/mailman/listinfo/users
